SHEARS.

SPECIFICATION forming part of Letters Patent No. 630,537, dated August 8, 1899.

Application filed May 26, 1899. Serial No. 718,368. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM (3. Human- DINGER, of Louisville, in the county of J efferson and State of Kentucky, have invented certainnew and useful Improvements in Shears; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in shears, and more particularly to such as are constructed with steel blades and cast-iron handles, the object of the invention being to so connect the iron handle with the steel blade as to reduce the cost. of manufacture and destroy all appearance of joints between the parts, and thus enhance the appearance of the finished product.

A further object is to so connect cast-iron handles to steel blades of shears that the joints between said parts shall be strong and durable, in which possibility of pivotal displacement will be effectually prevented, and which shall be rigid and effectual in all respects.

With these objects in view the invention consistsin certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View of a pair of shears embodying myinvention. Figs. 2, 3, and 4 are views illustrating details.

The handles of the respective blades are secured to the blades in precisely the same manner, and hence a detail description of one will suffice for both. I

A represents a steel shear-blade having a V-shaped butt-end 1, and B represents a castiron handle having a laterally projecting flange 2, in which an angular hole or opening 3 is made. The butt 1 of the blade is beveled transversely on one face, as at 3, thus forming a shoulder or abutment t; for the forward edge of the flange 2 of the handle. An integral angular lug 5 projects from the beveled face 3 of the butt 1 at a point intermediate of the ends of the latter and is adapted to enter the angular hole in the flange 2 of the handle. One end of the lug 5 is coincident with one edge of the butt 1, and the other end of said lug terminates at a point inwardly removed from the opposite edge of said butt. By thus disposing the lug on the butt the proper alinement of the inner edge of the handle with the inner edge of the blade will be assured and the two members'can be completely closed. The face of the flange 2 of the handle which bears against the butt of the blade is also beveled transversely, but in the opposite direction to the beveled face of the butt 1. By thus beveling the meeting faces of the flange 2 of the handle and the butt 1 of the blade two important results are attained-first, the cooperation of the oppositely-disposed beveled faces will serve to prevent lateral displacement of onepart relatively to the other, especially when assisted by the lug 5, and, second, the exposed meeting line between the butt 1 of the blade and the flange 2 of the handle will come at one edge of said butt, where in the finished article it cannot be observed. Thus by uniting the cast-iron handle to the steel blade, as hereinbefore explained, the joint cannot be seen without very close inspection, and the blade and handle will therefore have the appearance of being made in a single piece. The lug 5 on the butt of the blade being angular and entering a similarly-shaped hole in the flange of the handle, there will be no possibility of pivotal displacement of the blade and handle relatively to each other, as might be possible with a round lug.

After the blade and handle shall have been united, as above explained, the joint will be brazed in any approved way, but preferably by the dipping process.

I do not claim in this case the process of making the article herein set forth, such process being the subject of another application for patent filed by me on the 26th day of May, 1899, Serial No. 718,366.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a shear-blade hav* ing a transversely-beveled face at its buttend, of a handle having a transversely-beveled flange secured to the beveled face of the buttof the blade.

2. The combination of ablade having aV- shaped butt-end, said butt-end having a transversely-beveled face and a handle having a flange, one face of which is transversely beveled in an opposite direction to the bevel of the beveled face of the butt and secured thereto. I

3. The combination with a shear-blade havinga shoulder at its butt-end and an angular lug disposed a short distance from said shoulder, of a handle, a flange on said handle adapted to bear against said shoulder on the blade and having an angular hole to receive the angular lug on the butt-end of the blade.

4. The combination with a blade having a transversely-beveled face at its butt-end, and a lug projecting from said beveled face, one
